Memory Card Comparison & Performance Tests for Digital Cameras

Nikon D5300 SD Memory Card SlotWhat is the fastest memory card for my camera?

We test SD cards and CF cards in cameras to evaluate performance. Fast cards allow your camera to take more pictures in less time as well as transfer images to your computer faster. Buying a fast card does not guarantee high speed, your camera may be a limiting factor. We test a variety of memory cards in each camera to find the best cards. We also test several card readers with different memory cards to find which readers work best for each memory card.

Camera Memory Speed Tests

Every camera is tested using a variety of memory cards. The majority of cameras use Secure Digital (SD) cards, while others still use CompactFlash (CF) or both. We test write speed (in MB/s) as well as continuous shooting (maximum frames in 30 seconds) and recommend cards that perform best as well as which ones offer the best value. Below are the most recent cameras tested.

Card Reader Reviews and Benchmark Tests

External memory card readers allow high speed transfers between memory cards and computers. Many readers support USB 3.0, which is capable of 500 MB/s transfer speed. These readers are also backwards compatible with USB 2.0 connections and devices. USB 2.0 limits transfer speed to about 35 MB/s maximum throughput. Devices with internal card readers (laptops, monitors, etc.) may also be limiting due to using a slower USB or PCI bus.
